Hello guys, I got the follow PowerColor HD 6950 (here you go).
And I've tried to flash it from the 6950 bios to the 6970 bios with zero success.
While modding my current BIOS with the batch file posted on the guide and flash it on the current one, after i choose the to reboot the PC won't start up -> Black screen & no beeps from the MB.
Then I switch to BIOS N. 2 and Just flash the original back to the first BIOS.
I tried with multiple BIOSes and tried to mod some other with zero success.

Did you unlock voltage control and voltage monitoring in settings? Select that and then you can adjust the voltage to whatever. Monitor temps as you go. I had my voltage set to 1.2v I believe with clocks at 920ish/1400ish, with temps being in the 70's: everything ran fine.

It's not a reference card. Reference cards had single fan at the back and a black pcb. Your has a red pcb and dual fans. According to the reviews on Newegg, it can be unlocked, though it's not always 100%

well if you're card is a reference model you can unlock the vcore at MSIAfterburner.but if you're card is a revision model the voltage is lock in MSIAB. except if you use MSI Model card you can voltage tweak at MSIAB.

Well thanks, I'm just wondering if i'm doing something wrong while trying to flash my bios or is it the card it self.
After I'm flashing my BIOS the computer wont start up (no beep no picture -> stuck on pre MB bios while all fans running) Is it because the GPU locked?

Have you tried unlocking shaders with RBE?
<a href="http://www.techpowerup.com/downloads/1962/mirrors.php">RBE Here</a>
Load your BIOS into RBE and select 6970 shader count (under additional features, all the way to the right)
